Did a run in Black Temple last night on my 70 twink Monk trying for my main hand glaive. Reviewing her gear, and noting changes from the stat squish I see this little number looking very nice Band of the Eternal Defender - Item - World of Warcraft , that proc remains untouched by the stat squish of 6.0.2 and when compared to my 299 armor at her current level of 70, I was impressed. Granted this will most likely only be viable @90 if you are an enchanter and could enchant this ring for a bit more added effect, as the 70 stats on their own are not super impressive. However, with an enchant and this proc happening for you, you could end up with something very viable. Still, admittedly not a huge game breaker but certainly not intended.
Also there's, Bulwark of Azzinoth - Item - World of Warcraft, a more impressive 2000 armor proc that remains untouched by the stat squish, and of course this option is available to a larger number of players because it is not subject to the enchanter's exclusive ring enchants.
I'm not here to tell you these items are the key to downing the raid boss your group is stuck on, or that you will be god mode in pvp. I just figured it was worth some more investigation and I know no better community to share these findings with than this one. Enjoy.
